DDR Memory

<div style="text-align: justify; font-family: arial;" class="KonaBody"> <div id="ArtBody"> <p>Double data rate random access memory, or DDR RAM, is a memory technology used for storage and high-speed retrieval of data on a computer. It builds on the now-obsolete Single Data Rate (SDR) synchronous dynamic random access memory, and enables the computer to achieve greater bandwidth by double-pumping data. That is, the transfer of information is doubly fast with a DDR RAM.</p> <br /><span class="fullpost"><br /><br /><p>The more recent versions of DDR RAM are DDR2 and DDR3, which have faster memory bus signalling capabilities and clock frequencies. DDR2 operates at a clock frequency of over 400 MHz. The central powerhouse of your system operates faster and more efficiently on such improved memory circuitry, retrieving information faster and enabling you to run multiple applications.</p> <p>It must be remembered that if you want to upgrade the memory of a computer that uses DDR1, you cannot buy a DDR2 module and use it to supplement a DDR1 chipset. The slots for DDR1, 2 and 3 are different. Some motherboards, however, have slots for all these DDR formats. The booklet on the motherboard should tell you how to install additional RAM on your computer. Sixty-four bit processors often support more than 3.5 GB of DDR RAM. A 64-bit Windows Vista system, for example, will support memory of up to 128GB.</p> <p>A DDR RAM operates at a lower voltage than an SDR RAM, resulting in lower power consumption. Though it has the same architecture as an SDR RAM, a DDR RAM has 184 pins, instead of 168. It also has a single notch at the connector, not two. The bus width of DDR memory is 64 bits per channel. Most DDR-based chipsets come with matched pairs of modules and are made for processors that are 1GHz or faster.</p> <p>What a DDR RAM does is, it performs twice as many operations as an SDR RAM per clock cycle. The advent of DDR RAM was hailed as a landmark development that revolutionized the technology of random access, or volatile memory, but recent developments that have resulted in revision of DDR models have been just as interesting. At the beginning of the millennium, aspersions were cast on the use of DDR memory in home PCs, but now, all those doubts are gone and one can hardly live without the reassuring pace and efficiency of a DDR RAM. A big difference in systemic performance, coupled with improved BIOS efficiency, is an undoubted result of the quantum leap from SDR to DDR.</p><p style="text-align: right;"><span style="font-size:85%;"><strong>Author:</strong> oempcworld</span></p><p style="text-align: left;"><span style="font-size:85%;"><span style="font-style: italic; color: rgb(0, 102, 0);">Read More:</span> <span style="color: rgb(153, 51, 153);"><a href="http://computer-infocentre.blogspot.com/2008/10/sd-memory-cards.html">SD Memory</a>, <a href="http://computer-infocentre.blogspot.com/2008/10/simm-memory.html">SIMM Memory</a>, <a href="http://computer-infocentre.blogspot.com/2008/10/flash-memory.html">Flash Memory</a></span></span><br /></p> </div> </div></span>

Tips For Choosing The Right Computer For You

<span style="font-family: arial;font-size:85%;" ><span style="font-style: italic;">Submitted By: </span><a class="biggerlink" href="http://www.isnare.com/?s=author&a=Gabriel+Adams" style="font-style: italic;">Gabriel Adams</a><br /></span><p style="font-family: arial; text-align: justify;font-family:arial;" ><span style="font-size:100%;">Are you ready to purchase a new computer? Great! The choices can be daunting, though. Just looking at the price aspect, you can spend anywhere from three hundred euros to several thousand euros, quite easily.</span></p><div style="text-align: justify;"> </div><p style="font-family: arial; text-align: justify;font-family:arial;" ><span style="font-size:100%;">The first choice you'll need to make is whether to buy a desktop or a laptop. If you need any amount of mobility at all, we'd suggest a laptop. If you don't plan on moving your computer around or using away from your home or office, you might want a desktop. Desktop computers are easier to repair and are cheaper for what you get.</span></p><div style="text-align: justify;"> </div><p style="font-family: arial; text-align: justify;font-family:arial;" ><span style="font-size:100%;">Next, you'll need to make a choice on some of the major features and components of the computer.</span></p><div style="text-align: justify;"> </div><p style="font-family: arial; text-align: justify;font-family:arial;" ><span style="font-size:100%;">Memory is a big factor in determining how quickly your computer performs tasks - I would not buy a computer with less than 512 MB of memory. 1 GB of memory would be even better. If you are planning on doing lots of multimedia work or other tasks that require a lot of operating resources, you should probably get 2 GB of memory. Also keep in mind that memory is classified by speed as well as storage size.</span></p><div style="text-align: justify;"> </div><p style="font-family: arial; text-align: justify;font-family:arial;" ><span style="font-size:100%;">You'll also need to decide on what processor you want and/or need. If you're not familiar with the technical aspects of computer processors and you are going to need a processor that's more powerful than standard, you might want to consult with a computer expert to help you make the choice.</span></p><div style="text-align: justify;"> </div><p style="font-family: arial; text-align: justify;font-family:arial;" ><span style="font-size:100%;">You'll also need to choose the hard drive size you'll need. This is any easy choice to make - just see how much hard drive space you're using now, add in any increases you expect to need, then add some space for expansion.</span></p><div style="text-align: justify;"> </div><p style="font-family: arial; text-align: justify;font-family:arial;" ><span style="font-size:100%;">There are many, many different components of a computer that you'll have to choose. It's worth a little time to think about exactly what you need so you make the right choice the first time.</span></p><br /><div style="font-family: arial; font-style: italic;font-family:arial;" id="authorbio" ><p><span style="font-size:85%;">About the Author:<br /><br />Visit Virtua IT, your source for <a href="http://www.virtuait.com/">computer sales and service in Costa del Sol</a>: http://www.virtuait.com/</span></p></div>
